The tuner, matchbox or transmatch as it is sometimes called, will not correct the actual swr condition on the feed line or antenna, but it will resonate the antenna system as a whole that the radio sees on it's output and allows the transmitter to deliver as much power to the antenna system as possible within the design parameters of the tuner. The hybrid balun the preceding sections have shown that the current balun is limited by
